I just got from eBay an "ATHEROS AR5BHB92" for less than $10 (incl. shipping) and it turns out working perfectly OOB (so to speak... there was no actual Box!).

I installed it on the Gigabyte PCI adapter that came with my GA-Z77X-UP5 TH (replaced the module that was on it), rebooted and the WIFI menu appeared right away. I opened Network Preferences and it said a new device was found, acknowledeged that and I had WIFI working and detected as a regular Airport device. It is picking up the 5Ghz signal from my Time Capsule.

I got this card from a US Seller, received it within 3 days, all for $8.94. Here is the "Buy it Now" auction, it may be expired by the time you read this but they had many in stock: http://www.ebay.com/itm/350553868136#ht_548wt_1156 (or search for "ATHEROS AR5BHB92").

Attached are a pict of the module + some IoReg screenshots, hope that's useful...
